Personally I have bikes that I didnt put even $250 in and they have been good reliable bikes, but I did this by getting a used bike at a real bargain, one example is my Kulana moon dag bike, yeah not a high end bike and it has had several thing done that has it way over the $250 mark now but I paid $75 for the bike and an old 66cc CG engine and then got it running for pennies and road it that way for a while, only issue I ever hadon it was the rag joint over stressed the 14ga spokes a little and one of them broke on the rear wheel, It will be getting a wheelmaster wheel with 12ga spokes before long, I just dont like 14ga spokes with the rag joint coupler on them, it really bends than out.
The best bqng for the buck as far as an inexpensive build in my opinion is the Huffy bike, but the builder needs to plan on replacing the rear wheel in time and they should pull it apart and pack the coaster hub with good grease and get the bearing tensioned correctly, Ive got about 1200-1300 miles on my Falcon Huffy hub without a single issue because I did these steps in the beginning, the bearings and every part of the hub still look almost brand new after all these miles and I use the coaster brake as the primary brake on the bike with a C-Brake up front to help, it will get a Shimano 110 hub when its finally wore out its welcome though, the brak3s on the Huffy hubs are really weak compared to the Shimano coaster and no doubt the Shimano coaster is a far superior hub all the way around, but for the rider who just putts around every now and then at 30mph or less, the Falcon hub will usually do a good job if its kept adjusted and filled with a quality grease, this has been m6 experience on mine and I cruise rough dusty dirt roads and rarely ride under 30mph on that bike accept for slowing down to stop or make a turn.
One more suggestion is get a new and longer chain for the Huffy, and get on ebay and order a Sturmey Archer 22T rear cog/sprocket for the wheel, you'll be amazed at how much easier the bike is to pedal and bump start.
One bike I just put a 36T on the cranks and left the 18T on the wheel and its a dream to pedal now also.
