I own the i1photo LT and got it upgraded with RGB package (EORGBOM for 199$, 99$ with 50% off voucher, direct from xrite but you need to email after purchase) so it now work like any other top of the line i1 and it was way cheaper.
You only get to profile screen and printer with this package but i didn't saw any use for me of other bells and whistles included with top i1 packages at this time and still dont.
i1 photo LT could be quite scarce, i think they are discontinued.
