Saito 100 and a Fliton Extra 300 is a nice combo,or so I have read countless times,their Edge is aparently nice too.These look like more scale planes and from many reviews, I gather, that they imac and 3D well for their size.
You have to go to products to see the 330S..they have some other choices that may work for you also
