Gamelender went our of business in early 2007--we keep their review up for posterity's sake.
Gamelender certainly caters to more consoles (15!) than any other, including several legacy systems, but they don't have top support for latest generation of consoles, with no Wii or PS3 games available when we looked in March 2007. That said, if you have older consoles, they're the choice for you, with support for Xbox, Xbox 360, Playstation 1 and 2, Gamecube, Gameboy Advance, Gameboy Color, Nintendo DS, Nokia N-GAGE, PSP, Dreamcast, Nintendo 64, Sega Genesis, SNES, and even the venerable NES.
Of course, this wide console selection won't matter unless you own the console; over all of them, they have over 7,000 titles available, listed in eight genres for easy browsing. Probably based on this large console, and thus title selection, Gamelender claims to be the biggest online video game rental store.
Gamelender ships from San Jose, California, so mail times to the West Coast are excellent, but not so good to the East Coast.
When actually browsing through the titles, they don't offer as much information as many other services do. They list a box picture, a customer rating, publisher, genre, release date, rating, players, online, and some titles have a description, but none of these factors are hyperlinked, for instance, and there are no screenshots. Again, minor points, but ones other companies handle considerably better.
The site has parental controls, unlike many sites. Their FAQ is rather short, and doesn't go as far as we'd hope. Their Contact Us form appears functional, and they have an email address, but no customer service phone number. Gamelender does have an option to purchase rental games, which some renters will appreciate.
Prices: GameLender has a no free trial. Game plans are $ $19.95 for 2 games out, and $24.95 for 3 games out.
