HDTV Tuner: Will I be Happy?

[Mac]

Will I be happy with any of these?

Samsung SIR-T451
Samsung SIR-TS360 Direct TV
Motorola Voom DSR550

I have an NEC display with DVI input and a Philips analog TV with S-Video in.

Want to start simple and watch OTA HDTV.

Had Motorola Voom DSR550 with Voom.
Pros: Box is fast, provide good PQ, good HD tuner.
Cons: No guide.

I would be very careful buying an old VOOM box, be SURE that it has an activated card in it so it still works.

I had the Samsung 360 for a while.  If your only watching OTA its fine.  I had D* on it as well, and there were audio sync problems on ESPNHD.  It was a box problem as I swapped mine out and the problem was gone.  The 360 has a fast and easy-to-use guide.  Check ebay, they usually run between $30-$50.
