Sun Crusher 7
Sun Bicycles - Product
Surprised I'm the first to post on this (that I know of). Steel frame, 170mm rear, 7 speed derailleur. 3.5" cruiser tires. 80mm 36h rims. Vee brakes. No idea whether it will fit 3.7/3.8 Surly rubber, but it doesn't seem like that big a stretch.
A few disadvantages compared to the $1500 variety (no idea how these are priced), but I personally am drawn to the longer chainstays and generous rack/fender mounting points (no fenders listed yet).
Interested what others' takes are. I'm unusual in that weight doesn't bother me and I prefer longer chainstays. My uses would be mainly as a mountain bike and only a little bit in conditions where mountain bikes would be unusable. The handlebars would have to go, and I might need to correct the seat position to be more MTB, less cruiser.

Squeezing larger rubber beneath the V-brakes looks fairly questionable. Add a frame&fork mounted cable stop and those same bosses could be used for cantilever brakes which have no trouble coping with fat tires.
The sun spider AT bike looks slightly more capable than the crusher7,
spider at least has an MTB looking aluminum frame rather than hi-carbon steel. Both of the sun fat-bikes acutually manage to make the wal-mart fatgoose look like nice ride by comparison.

Looked at the geometry a while back, and it seemed to be really loooooong "top tube", which they get part way around by using those long sweeping bars with a short gooseneck. Make sure you're OK with that and whatever you use for bars.
Can't find price for Sun 7-looks like a big step up from fatgoose to me, tho. Gears, brakes, and "alloy" parts. Don't see where weight could be cut easily, tho. And the frame
might be kinda close to those 3.5" tires?
I was quoted under $600 on the fly by a LBS today.
If tire choices are a concern, it might be a step down ... The goose has 5.375" of clearance at it's narrowest location.

I got all excited when I found a shop selling hubs; the pic was a generic-looking casette hub. But the description was coaster brake. The specs for the 7-speed list it as a freewheel hub. Probably 8mm chinese-steel axle roughly similar to a cooked noodle.
I can't find one of these locally...
Two questions for those fortunate enough to have an LBS with these in stock.
1. What is the distance between the canti-posts on the frame?
2. Will an Endomorph 3.7 or similar 3.8 tire fit the frame or is it stock 3.5 tires max?
If the tires do fit, you may want to consider the switch to cantis to get more room for tire. The linear pulls have only so much room.

Edit: Those V-brakes seem ridiculous but the canti pivots are useful.
If the frame bosses work for V-brakes, they should probably work for cantilevers too (so long as you dont go with significantly wider rims). Typical cantilever post spacing of around 80mm is applicable for regular narrow 20-25mm rims, if the rims are another 60mm wider than that, the extra width needs to be added to the post spacing too in order to keep the post in same relative position to the rim braking surface, not just constant 80mm post spacing regardless of rim width.

The wallgoose parts make much less expensive trashcan filler. I would also guesse that the 3.5" tires on the crusher might be a chainline clearance limitation, trying to go wider might requires different drivetrain chainline related components and/or frame offset.
If an upgrade project is in the works, starting with the sun spider seems like a better plan than the crusher, at least the spider is CrMo instead of hi-tensile.
