The VX and the GTI are very similar in ride and speed. You will get more gismos with the SeaDoo, and more reliability with the VX. Fuel mileage will be similar with a little advantage to the VX, which is the most fuel efficient ski on the market. Prices really vary from dealer to dealer, and from different locations. This is probably the worst time of the year to get any type of deal, because it is peak season (if you are in the US). Don't expect to see dealers budge too much. For both the VX and GTI, I'd look for left over skis from last year or even 2 years ago. They haven't really changed much, and dealers are often willing to come off the price to move old inventory.
You need to do some comparison pricing in your area then post up what they are offering (including warranty, with or without a trailer, accessories). Then we can tell you if it sounds reasonable. Out the door prices vary widely, because of all the idiot fees some dealers throw in. I don't know what SeaDoo charges for their extended warranties, so depends on price. Many Yamaha dealers will include the 4 year extended warranty at no charge to move a ski, but this varies especially this time of year. You probably need it less with the Yamaha, but not a bad thing to have if it is free.
The VXS is like a Volkswagen with a Corvette engine. It has the same hull as the VX, but with a 200 HP engine versus the 110 HP engine in the VX. Look at the VXS if you want to go very fast. With a stock speed of around 67 mph it is the fastest normally aspirated ski on the market.
