20Da vs Hutech

I have a 20D and it works great on some subjects but would like more red. Which is considered the best way to go? The new 20Da ($2199) or the 20D modified by Hutech ($1995). Both seem to have the option to use VLC filter on lens to do daylight. I plan on keeping my existing 20D for regular daytime use. I am leaning towards the 20Da do to the half mirror and LCD focus. Has anyone compared the two? Here is a short exposure of M27 with my 20D & C11.

Thanks

Sam
