Ha good to see another Aussie on the forum,
IMHO best buys (features V cost) here in AUS are both HiTech either the flash5 or laser6, best prices i've found is at www.radiomodels.com.au in Perth, i've bought over the net and phone from them with no problems.

just a word of advise, join a club and find out what spare frequencies they have (or least used) and order the set with these crystals, it'll give you more flying time (less clashes) and save you some cost later if you change.

As your a fellow Aussie i'll take the liberty (at the risk of getting flamed AGAIN) of sugesting you have a look at the SPAD site www.spadtothebone.com it'll save you some money on the next plane you build.
