Chris -
What is the budget you are looking at? I needed one also, but did not feel like shelling out close to a grand on the thing (since I only paid 1200 on my RPTV), I found an open face audio unit from Lowes "Ready-to-finish" area.

At $108 per unit, I used a pair, with one on each side of my RPTV. The units are a little shorter than the RPTV, but balances out nicely. They are real wood, and you must finish them yourself (or leave natural). I was able to finish both units (2 coats each) with one quart of the minwax stain/poly one-step product.
I will try to take a picture of my set-up tonight and post it here.
