I need an external USB unit. What unit gives the best performance for least grief?

SB Live 16 bits, 48KHz, works OK, obsolete
SB Live USB 16bits, 48KHz, < $30, obsolete
SB Live 24 PCI 24 bits,96KHz, <$30, works not too bad considering cost.
SB Live USB 24 bits,96KHz < $50, works OK but consumes a lot of CPU cycles, requires USB2 B mode, problems with really achieving 96KHz, stay away from this one.
SB Audigy 2 ZS 24 bits,96KHz, < $80, high noise floor, I've rather have the Delta
Chaintech AV-710 20 bits, 48KHz, <$25, consumes low CPU cycles.
Delta-44 24 bits,96KHz, < $150, performs as advertised, low noise, best card I own, don't forget to buy adapter cables since it uses 1/4 phono plugs.
Given all the time I've wasted on trying to make some of these cards work, I should have bought the Delta in the first place and I would have saved time and money. If your card is worthless, and you don't have the money the Chaintech and the SB Live 24 PCI are not bad considering their under $30 cost. But if you want to seriously play with SDR, maybe build your own or some of the designs available out there save your money and buy the Delta-44.
If I have time tonight, I will slip the Chaintech card in my new PC and give you a report of how well it does.

Thanks for the reply Cecil, I've only noticed one Chaintech card that claimed the 192 Khz sampling it was the AV-710. The lack of information even on their specs is what I'm running into. May have to break down and buy a Delta 44, I was hoping I could find a bargain on a card someone else had tried. I'm kind of new to this group, but seems a large majority have Delta 44 cards. Thanks Joe k0ivk

If it's the same card I don't know, but they have a card I bought for
$23 from Newegg, it claims 192KHz, so I went ahead and bought one.
Nowhere were the specs clear on it, not even at the manufacturers, the upshot, after I bought it you discover that it does 192KHz, and 96KHz only on the digital port and not the analog port. It did have one nice feature in that with SIO4ALL you could use DMA transfers so
the CPU usage went way down. The board is only good to 20 bits but that is better than 16.
If you want the exact model I purchased, let me know, and I'll look for the card.

Hello Everyone. I have been successfully using a Santa Cruz card for my SR40 and SR
5.0s but would like to try a 96Khz sampling 24 bit card. I would buy a
Delta 44 card but hesitate to spend that much for a $30 receiver. I
looked at the Creative Live card but was discouraged by the dual purpose input/output arrangment. I use the Soft Rock rx on the Santa
Cruz card and feed output to the on-board sound card using Digipan to
copy PSK31. I would hate to mess that system up to acheive wider bandwidth. Has anyone had success with other less expensive 96Khz 24 bit cards
that have separate stereo line in and at least 2 stereo outputs? I notice Chaintech has a card that claims 192Khz sampling,and lots of
inputs/outputs!!! Has anyone tried it? Thanks, Joe k0ivk
