The last time I rode MTB was probably 20 years ago. I'm easing back into things and trying to do so on the cheap (mainly just riding around w/ the kids for now, but at some point I may start doing more serious trail riding). Anyway, I have a 2005 Trek 3700 I got on Craigslist and have some vintage (read: old) XT derailleurs on the way via Ebay. I was trying to find some compatible XT or LX shifter/brake combos on Ebay, but am also seeing some new 3x7 shifters on Amazon, etc. I know zilch about modern components and am not looking to break the bank or go gung-ho. So if anyone has some recs on modern 3x7 shifters in the sub-$100 range that are decent, I'm all ears.
