howdy! and welcome!
if you are saving up for a mod (not a bad idea to get something solid that will hold up and last - especially with the deeming looming and the associated uncertainty there - don't get me wrong - not advocating panic, just prudence) may be worth looking at some that will keep you from having to upgrade for a bit...
that being said - what are some of the keys for you? form factor? single battery vs dual battery? size or weight?
a very reasonably priced single battery mod like the evic vtc mini might be worth looking at - though, one of my current faves is the sigelei 213 - the carbon fiber/ gunmetal version is six kinds of shmexy, comparitively VERY light for a dual battery box, small form factor, plenty of power (you don't have to max it out - running lower wattage on a dual battery box just means you get much more battery life between swapping batteries) and TC capable as well... pic below is the sig 213 next to evic vtc mini for comparison (keep in mind evic is single battery box, sig is dual)
