If you only need 2 inputs the Delta 1010 is overkill anyway, it has 8 analogue ins/outs and inputs you're not using is wasted money you could be spending on better pres/mics etc.
The M Audio audiophile 2496 is a 2in, 2 out card which would be in the same ball park as the Delta quality wise but is only $99 or so.
In fact a very respectable 2 channel budget recording chain is the audiophile card combined with a DMP-3 dual channel mic preamp.
If you really wanted a breakout box and a couple of extra channels 'just in case' the Delta 44 is a 4 in, 4 out card costing around $150.
That's stuff I have experience with anyway and I can vouch for it, you could also look at the presonus firebox or the M Audio Firewire 410, these are both 2 channel firewire interfaces with mic pres both costing $300. (The firebox is the 2 channel version of the firepod wheelema mentioned).
