Segways are divided into the categories of gen 1 and gen 2. The gen 1 are the older machines that haven't been manufactured since 2006, and the gen 2 ones are the newer ones.
Generation 1 machines include such models as p133, XT,e167,i180/GT and i167/i170. You may still be able to find some of these on the market, as well as parts for these, but primarily you till find the second generation machines such as model i2, x2 and the various manifestations of these such as the patroller or the golf variations that are specially equipped for their purposes.
Here are some of the generation 2 Segways that are currently up for auction on Ebay.
