You should also look at the Tenga Flip from Japan.
Fleshlights/Fleshjacks are heavy and awkward to clean. Flips are smaller, lighter and wash up easily. There are lots of different inserts for Fleshlight with various levels of tightness and suction, look on their own forum for advice on which to choose. With Flip there are three buttons you use to change the suction and tightness to get the effect you like best.
Disadvantage of the Tenga is that it is far too tight if you are a big boy, it's only suitable for Mr Average. The Fleshlight can go all the way up to porn-size cocks, for anyone lucky enough to need it.
