I know there are adapters from ide to CF cards.

ide adapter

CF card

but the adapter is $15 and card run from $65 for 128gb to over $100 for 256gb.

Here are 2 other options for hard drives which are much cheaper.

160gb hard drive

which cost $10.99 and
320gb hard drive

which cost $59.99. Would these hard drives work as cheaper options?
