Thanks,
I think at this point I'm in the "I've more than gotten my money's worth - the old 880L is fully depreciated so it's time for a replacement" position. I'm not convinced continuing to throw darts is worth the time, and with a budget of ~$350-$400 I'm willing to drop on a replacement I'm pretty sure I can find one that's reasonably future-proofed for the next 4-5 years. This one's served us well enough, but it seems like it may be time for a change.
Thanks again, I appreciate the responses and suggestions from you.
