Sure, I don't see why it can't work as a first AEG, but allow me to express some brief concerns.
This argument has been put through the wash so many times in the past, Agent J (as he was known) made a huge copy-paste argument to prove some points, and it was a damn good one. In the end, the agreement was that TM internals, kept stock or mildly upgraded and not beaten to a pulp by irresponsilbe use, can and will last upwards of 40000-50000 rounds, some even going twice that far, at the cost of less durable external material. Meanwhile, for a slightly higher price, the CA will give you a solid, durable external structure (for you clumsy people) and a slightly higher FPS that, quite honestly, will probably not hit the 40000 round mark.
Allow me to throw my ultimate suggestion out there, go TM. After 28 months, a 6-figure shot count, 330 FPS, stock gears, and stock motor, mine just simply refuses to die. Quite honestly, I don't understand it anymore, but it works and I like that. I expect all my guns to simply work, not just look good, even though after the 28 months it's been in my possesion, it still looks pretty damn good. By the way, Marui's with Guarder metal bodies are a mere 20-30 dollars more than a stock CA from UNCompany, just so you know.
However, do not let this and other interesting facts deter you from getting the CA. It is a solid stock platform as well, giving external prowess. Just don't expect to get 6-figure shot counts out of it is all. If you don't plan to go that high before eventually deciding to upgrade or revamp, then go ahead and be lazy (^^).
