I agree with you on the size of these things - the companies then sell, separately of course, platforms to raise them up to a decent height. Once you figure in the cost of the platform for an Arcade1Up unit it is quite prohibitive - and you are limited to those games installed, unless you wish to go through a bit of hacking.

Of the bunch, the iiRcade seems to offer the best bang for the buck so far just by offering a legal way to expand your game collection without shelling out another $300+. Not to mention the floor space another arcade unit would occupy in your home.
