I just recently got a 1Mcp and a 25Mcp projector a few weeks ago:
the 1Mcp halogen I got is pretty much equal to my TK40 with a tighter beam and artefacts, so a little more throw (but very negligible), very tight hotspot, but much better color rendition. I got a very good deal for it (10$ for a 30$ projector), so I can say despite the 15 minute runtime, it was worth the money.
The 25Mcp HID Eliminator spotlight I just got... well, it beats my TK40 both in throw and brightness, but it's got a frosted bulb, so from what I gather it should do much more than just that. It only beats the throw of my TK40 by about 20%, but for the size of the reflector should beat it by over 100% with a transparent bulb, which I will order in a few weeks. Brightness wise, I wasn't that much impressed on a white wall, but taking it to the field, the spill was much more impressive, making the spill from my TK40 look ordinary, which it isn't.
I got the 25Mcp Eliminator HID at a local store, paid 100$ for it and think it was worth the money as is. The up side is that it has the 12V cigarette lighter outlet I can use to recharge my batteries for other lights (sweet!), but until I can put my hands on transparent bulbs, I'm not very impressed with it. The TK 40 is much more portable and they both have comparable runtime on high.
I'm waiting for my M1X to get in the mail, so I know I won't turn that thing on until I get a new bulb... well, I might do some comparisons in the field being a flashaholic and all....
Hope this helps answer your question
