Audiophile Usb And Pre-amp, Any suggestions? Options

[littlewonder]

Hi,

I first wanted to buy an Edirol ua-5.
But the salesman told me not to buy this module because of a strange problem.
He told me that when you start recording, the first measure was "slow", like a tape that is played too slowly. (its config is OS X 10.2.x, g4 450, 380Mb, Cubase SX) (any person who noticed this problem?)

He adviced me to buy the m-audio audiophile usb.
This module looks great. (any experience?)
But it has no pre-amp.

Can you tell me about a cheap pre-amp solution to use with the audiophile usb?
I would like to be able to record voice and guitar.
The quality do not need to be very good.
I just need a mobile-cheap solution.

Thanks in advance for your suggestions.
Thomas.
