Shopping for our first boat

Well the local boat show came and gone here up in Saskatchewan Canada, and the snow is quickly melting away. My girlfriend and I are wanting to buy our first inboard boat. We looked at all the new models at the show which were all very nice (Mastercraft, Malibu/axis, Nautique, Supra/moomba, Epic) but decided to buy used, because like many people we can't afford a brand new one.
After looking and talking we narrowed our search down to a few, the newer style X2, 04-07 X-Star, and would love a X-15 but most are out of our price range.
Moomba Mobius and Supra Launch 06-08
Super Air 210 04-08, i know they changed the hull in there but I dont know what year and what the difference is.

I am just wondering people's experience with these boats, what the pro's and cons are of each one and if there is anything special to look for when looking at them.

I know the MC's are more expensive but are supposed to be the best quality, The moomba's are more in our price range and seem to be adequate for what we need and the 210's are in between.

We board and surf recreationally and love just being on the water.

Thanks for your help
