I think the price is about right if you are talking about the Hirobo version. You can try Galaxy (852) 2615 2290 to get another quote. I think they carry all three of the Hirobos.

Personally, I wouldn't go for a .15 unless you really want that size. They are not so stable and become a handful with any kind of wind. What level flyer are you? If you are a decent flyer with transportation, you can consider a Ramber 30 from Radar or a Supersport 30. They are relatively small planes that are a pleasure to fly. In fact, just tell me what you're looking for and I can give you my .02

I am also in HK and my recommendations are:

For quick building kits, go to Radar... they are definitely the best.

If you are looking to buy into the hobby, I'm selling some of my planes
