Just a quick easy to read breakdown. and yes this is my opinion (and some testing done as well) so anyone is welcome to disagree as it is a forum for discussion.
Mods people are recommending that i don't agree with
Wismec (not including the predator) - poor quality mods, not worth the money IMO. plus OP wants temp control and wismec temp control is iffy at best
Alien - love the alien but for temp control, it is iffy at best
DNA75 mod - expensive and I'm not a fan of the chip's performance. the DNA200/250 is a much better chip and I love them but not a fan of the 75. plus we are talking 60-80 dollar territory here
DNA200/250 mod - excellent for sure and TC is amazing for SS but steep learning curve and 100+ dollar range makes it a no go to the OP
YiHi G class - possibly my new favorite mod but 200+ price tag makes it a no go. Also a semi steep learning curve. less then the DNA mods IMO but more then the rest
Predator - nobody has one yet, myself included so i cna't recommend a mod I never touched or know anyone who has one
IPV6/IPV8 - TC doesn't really work well at all on them.
Some good choices in OPs price range
Hohmslice - #1 choice by far. TC any wire so all your premade kanthal
coils can be temp controlled. small learning curve and all adjustments made on mod. no apps or PC required. only 30 bucks. 2 amp quick charging and outperforms the DNA75 chip at half the price. can use 4500mah batts in it (single 26650) for better battery life then a single 18650 mod
Battlestar - it's a dual 18650 mod, but can TC SS wire really good. just a step below the big 3 (DNA,Yihi, and FSK) and under 40 bucks. with dual 18650 batts battery life will be great at low watts
