Im on the fence about getting one of these. Im going to actually buy any HuCARD that I want to play, but it could be useful with those translated roms.
In the future I'll buy this Everdrive (it certainly seems like the best card yet), but I have purchased the NeoFlash and the homegrown one (designed by a fellow forum member) because there are a handful of translations and pricey HuCARDs that I want to play on a real console.
For me, it's worth it for a handful of games.
I own tons of games, but I am still infatuated with a few that are "out of reach"...
