Why are GBA FA Linkers cheaper than the others?

[capitalcarnage]

I found this Flash 2 Advance Pro Linker &
Flash Advance Pro 256m ramcard to be about 120.00

If i buy from another site, such as gamegizmo, they sell a different brand for almost 200 DOLLARS?

WHATS THE DIFFERENCE?

Is one better then the other?

THey can both play downloaded GBA ROM games, right?

One uses USB so is quicker than the parallel port. Have a look at Lan-Kwei, I got a 128mb F2A for £61 delivered.
