What bike for me?

[1150A]

Hey Guys,
New here, and from my research, it seems like Gasgas bikes would work out great for me. I'm coming from a mountain bike back ground and am looking for something reasonably light. I'm also not a very large person @ 145lbs and 5'7".

I'm still a novice to moto, but have ridden and owned bikes before. My first bike was a KDX220 which I loved. However, it felt slightly top heavy and although super reliable, it felt dated and I just wanted something new. I ended getting an awesome trade + a little cash for a 2009 Husqvarna TXC 250. With the tractability of the KDX, I felt at home on the TXC. It feels great to be a modern bike with updated suspension and coming into corners/berms felt much more natural. BUT, little did I know, the Husqvarna is and definitely feels even more heavy than the KDX 220.

Now, I want to go back to 2t for the lighter weight and cost. Buying new is not really an option for me as I'm a college student, at the same time, I'd like something newer or more modern than the KDX at least. I'm looking for something light weight and has that low end like the KDX does.

The bikes that fit my budget are:
03 Gasgas EC300
05 Gasgas EC250
07-09 KTM 200 XC XC-W
09 Husqvarna WR125

Any suggestions would be greatly appreciated!
