MAHA C9000 = 3 year warranty
LaCrosse BC900 = 1 year warranty
...I've read on here that the MAHA C9000 has some better parts though though I have not found people saying that their Lacrosse BC900 has physically broken, though with earlier versions, a few have appeared to have melted down.
I am considering both of these currently as well. I am edging towards the LaCrosse because I dig the readout for each cell (as opposed to scrolling through with the C9000).
