IDK much about mics, but from the stuff that's been listed the 750i is the mic version, extra $$$ though. Another option: the shure 215, or at least some models of them, have a removable cable, you might be able to find a cheap aftermarket cable with a mic, the official one is a bit $$$. The audio technica IMs have removable cables, no official mic version afaik but i believe there are aftermarket mic cables.  Could always buy just the cans, and add the mic in later when you have the funds.
 
That said, there are tons of sub-100 inears with mics from reputable brands like Audio Technica, Sennheiser (momentum in-ears, for isntance), RHA, etc... they might not get much love on here, but still could sound great- I'd suggest reading around/asking on the 'Discoveries' thread if nobody has a satisfactory recommendation here- I think they give a decent amount of attention to lesser known stuff (just search 'discoveries'). (some other resources: head-fi-er joker has a thread here recommending stuff by sound signature: http://theheadphonelist.com/earphone-buyers-guide/  Innerfidelity has their wall of fame too : http://www.innerfidelity.com/content/innerfidelitys-wall-fame-ear-monitors - the wirecutter also did a pretty big inear breakdown/ranking not too long ago)

Some people have reported issues with the i version of the RHA MA750, however, you have a 3 year warranty and it's probably your best bet if you want a good iem with mic and remote. The remote cable for the shures seems to be awful.
