Help with choosing a Boat

Hey everyone,

First of all great site, I have been reading some of the posts around and are VERY helpful.

I am about to purchase my first boat. I am a very novice rider and I do not have THAT much money to spend. I am buying this boat with my mother and a friend so it won't be 100% wakeboarding what they will do (I will :P). Anyway we have been running around different boats, and there are so many and so much info that is really hard to digest specially by having such little knowledge / experience on the industry.

I have been pushing really hard to have something wake board friendly, but my biggest worry is to get something that will not do good on salt water or with mild tide.

Our budged is around $15,000.00

First we were looking at a Sea Doo Utopia, after further research we have discarded it.

Now we are looking at 2 boats:
Malibu Skier ($7500)
1994
20'
2350 lbs
Mercury Cruiser 5.7 TKS
260 HP
455 hours

and a

Gekko Bazooka ($12,500)
2001
21'
2600 lbs
Mercury 350
360 HP
450/50 hrs (new engine)

Now, I have been reading reviews of these two boats, but if anyone has any comments / suggestions on these boats or recommends a different kind of boat it will be appreciated.

We have been looking at Tahoe boats, but the sport models are fairly new and they might be slightly out of our budget.

We live on an apartment complex that has a dock right outside, and already have a lift for the boat to lift it out of the water. (the boat will sit on the lift).

Any input is appreciated.
