If by alternative you mean meets all the specs including legal on golf courses, then I think Atomic is it for now, but there are a lot of Chinese models starting to show up - maybe someone knows those. But, I would recommend the Atomic - AC, windows, can be street legal, etc. Lots of features for not much more than that custom golf cart.
There appears to be a dealer in Wildwood which part of The Villages is in.
