College Student Looking for Best Bang for Buck

Hello all!

After another cheap Schwinn started to crap out on me, I've been looking around for a replacement. I can't afford to drop a bunch of cash on a bike at the moment given my cut hours, college student, etc. I'm not really wanting to spend more than $200 on a bike and any immediate needed modifications. I know that big box bikes are usually not worth it, especially at my budget, so my goal is to get something used. The issue I've found when searching for a used bike is that there are plenty of bad options. Every time I find an okay looking listing, the bike usually ends up being not worth it.

So, I have a few listings in mind that I'm trying to rule out and want to see what you all think. I guess immediately this will be my commuter bike around my campus and maybe into the nearby area. I'm wanting to get into biking more in general, maybe not crazy stunts but probably trails around town and maybe trails at National Parks or when I'm out camping in my Xterra. I act like a mountain biker riding on campus, bobbing a weaving through normal pedestrian traffic, so something that won't start to crumble because I have too much fun with it. I don't mind general upkeep, but I've been looking for listings for bikes that have already been sort of tuned I suppose. Other than the bike itself, I'm like 6'1" so I suppose if the wheels are on the smaller side, a bigger frame would be ideal. The Schwinn AL Comp that's currently falling apart by the days felt a little on the smaller side.

Anyways, I found a Transeo 2.0 for $150 with recently done hydraulics for the brakes (probably going to sell soon). A GT Aggressor Comp for $150 (leaning towards this). A Trek 3200 for $150 (looks like a 3500 and claims to have been recently tuned up and has disc brakes). Another Trek, 3500 I think with some extras for $150. This next one would need some love but I found it interesting, a Fuji Sunfire 4.0 for $85 bucks.

So if any of those look like they'd be remotely worth my time, any input would be appreciated!
