Only a few radios have microphone plugs on their remote face.
ALINCO
DR-735T. $295. I thin the mic plugs into the faceplate but check before buying.
ALINCO
DR-635T $289 (cross band repeat). I love their round 8 pin connectors. Everyone else uses the crappy RJ-45 connectors.
Both are under $300 at Ham Radio Outlet (they usually have the best prices, great service and free shipping).
Also look at a Yeasu FT-7900R. It's under $300 but has no mic connector on faceplate. Most Yeasu rigs include a faceplate separation kit. Check before buying thou.
Kenwood TM-V71a is nice too but it's $335 and they don't include a separation kit (expensive)
YAESU FTM-100DR is a new radio with digital or FM modes. It's very nice and only $309.
Several days ago they had huge Dayton Hamvention discounts on many radios. FT8900 quad band was only $279
