sew your own diapers

Hi Mamas!
I am new to diaper sewing and have been looking at Sergers.  I know that most feel Babylock is best due to it being maneuverable around corners.  I found a used one on my local Craigslist, it's model  BL4-625, does anyone know if this one will work for diapers?  It has 4 spools.  Thanks for any input/advice!

Hmm, I can't seem to find any info on it at the www.patternreview.com and they're usually pretty comprehensive.  I have a newer Baby Lock Imagine serger and I absolutely LOVE it, but I don't know anything specific about the BL4-625 except for that Babylocks have always had a good reputation... will the seller let you come try it out?
