I too have an SL-1+. It comes with a DC power connector; I wired it up to a 9v battery connector and use that. A 9v heavy-duty alkaline can last a long time, given the SL-1+ only draws 10ma.
They (TigerTronics) also now (as of 01Dec2006) sell a USB version (includes a built in soundcard) that gets its power from the USB connection. No external power required. I'm planning on ordering one of those; will use that with my K2, & the original one w/my FT-817. For those interested, see www.tigertronics.com.
