Digital Camera memory - storage methods?

Hello, can anyone please help me out with the following question i have:

I have a 2gb sd card (sandisk ultra 2) for a 7 mp camera which records movies in mpeg4 format. once the card is full, is there a way i can store the pictures+video clips in some portable device (other than using a laptop/computer), so i can repeatedly get my 2gb memory space free again for further use? i do not want to buy multiple high speed sd cards, they are expensive. is there a storage device for sd cards to do this? if so, how much should i expect to spend to get one of these? any recommendations?

thank you for reading, have a nice day.

A "photobank" is what you need. Check out

You could try something like a QCool III card reader, its $99, but you also have to purchase a laptop hard drive which could vary in cost and size.

There may be something of use here.
