I would also would love to use BAL eventually. I'd love to be able to use stuff that I already bought for now... ;-) Thanks Do Edited by user Sunday, June 19, 2011 9:09:23 PM(UTC)  | Reason: Not specified

Your best bet will be the IVY-III. Sorry.

Adding an output stage like the IVY-III considerably improves performance. Notice I said output stage, not I/V stage. :) Edited by user Thursday, June 23, 2011 6:16:39 AM(UTC)  | Reason: Not specified
