I never owned the Mits, but I DID own the Sharp DT-500(510 predecessor).

I thought it threw a fabulous picture, BUT the bulb LITERALLY BLEWUP(I could hear glass rattling around inside) at about 650 hrs.
No jarring, no temp extremes, just blew up on it's own.

No one was even in the same room, I went up stairs to get a drink, and when I came back downstairs there was no pic...
Some of the other owners of the 500 had some issues like this as well...

I won't say that the PJ has serious issues, maybe I was just unlucky.

I have a Panasonic AX100U LCD PJ now, and I think the DT-500 had better picture quality, I have taken some identical shots that show me that the 500 was sharper as well...
The AX100U pics were at 2000 hrs, and for all I know the 500 may be on it's third bulb by now..
I basically moved to the LCD after that, because of placement issues.

The 500 has many owners that are thrilled with it though, so if the 510 is as good PQ wise as the 500, then it will throw a great pic.

Sorry I couldn't be of more help.
