241HD is a good route, 271 appears to be good. The 241HD is proven, remember when everybody thought the NV5600 was way stronger than the NV4500. I know of a big HP puller that broke 2 HV5600's and once he changed the input shaft on his 4500 he never had a problem. He even built a puller last year and put in a NV4500 in it instead of the 5600. Point 271 looks bigger, and stronger and may very well be, but the 241HD will handle plenty of abuse!!
I needed a charger to support my needs and the holsets just don't cut it.
