Great posts and useful information everyone.

Here's a remote solution the for Insignia IS-TV040928. ( I did the Best Buy open-box thing last week)

Went to Wal-Mart and purchased a Philips PM335 3-Device Universal Remote. Entered Mitsubishi TV code 102 (per the instructions at [Link: insignia-products.com] ) and it works perfectly!

Channel up/down, Vol up/down, Numeric input, Menu guide popup and controls, and device input popup and controls, are verified working.

With tax, the Philips PM335 cost about $8. Two AAA batteries aren't included. All said and done, the remote and batteries cost $11 - and everything works!

Hope this helps.
