I actually did calculate.

900-1000 ec's for the rep, 400 EC's to reforge weapon, 370 EC per armor piece--there are 4 pieces. So all that is nearly 3k EC's--2,880 to be exact. If you get a good deal on the rep, it can be slightly cheaper.

Reshaping on the other hand...infinity. I forked out well over 1k EC's on my wizzie's r8 reshaping, and 2k+ EC's on my archer's pants.
