Wellcome to PL and don`t get scared away by all the "propellerheads". We all have to start somewhere, and I guess morst of us have owned/owns a cheap China projector. All of us (i recon) feel that it is money out the window, but at least we have been able to shoot some cheap beams for starters, and found out why it is cheap.
As for the specifications, I don`t quite get things to fall into place.
Red 635 300mw would be bright, but it does not say anything about the beam quality. I guess you will have a really fat red beam dominating.
Green 532 100mw sounds about right and it is hard to do something wery wrong besides TTL modulaton.
Blue 405 200mw is really not usable in this setup. 405 is almost invisible to the human eye, and will not do at all. Look for 445-450nm and you get better colorbalance.
Scanangle 60" is great, but with 30"pps its hard to beleive in that pricerange. Ask for pictures of ILDA testimage from actual projector. If you then post the pictures here, we can give you a lot of information based upon that picture alone.
I highly advise you to keep on reading this forum to get more information.
