Top of the list at the moment is the Espresso Slope Glider. Why?
Well I challenge you to find a better built, better finished model at the price !
There is better out there such as the Opus or the Extreme, but not at this level of completness and quality whilst being anywhere near the price you will have to pay for it.I shopped around before buying this model from go gliding, and I looked at blaster, dragon and lots of other models of a similar spec and not one came in at anywhere near the price I paid for the espresso.
If your in the market for a light, strong moulded glider to throw around the slopes, then I do give this model a strong recommendation.
Before you think, Oh yeah and what's the catch? I promise you, I have no connections at all with either John (can't remember his second name) of   Go Gliding  or the Manufacturer of this model or any others for that matter.
I Like this model called Arising Star, from Seagull Models
I've been teaching someone to fly and I had to admit that after getting to grips with this model myself,
I have managed to get the model to fly safely at a fast walking pace.For the price this model represents a great entry into powered flight. Mine uses an old OS 40fp engine. Take offs need the full length of the strip but once up, it flies on 1/4 power and I can get 30 minutes duration using the supplied fuel tank.
The model went together quickly and I have not needed to strengthen it anywhere. I got mine from Barnstormers  was very happy with the price.
