Welcome mate,
Looking at G's (the older model) you won't have trouble finding one, the market is pretty flooded with them. As you've said the timing belt and water pump are common things to go but should be fixed at the 60k service. The owners here don't really seem to have many problems with them at all.
Difference between the n/a 2.2 and the turbo is such that many of the drivers with the 2.2 wished they bought the turbo after having driven it. You can pick one up pretty cheap and you'd have a sweet daily driver.
Other guys will tell you more soon i have no doubt
