The OEM 1301 module is 85 bux if your picky friend has deep pockets.
I've heard good reports about the cheaper aftermarket ignition modules across the board. My only personal experience has been with a 2-piece setup for an old-style Husky 61 and it's worked out great. Stens sells a 1301 MS250C replacement for $25..., probably the same as some of the others for $12.50 elsewhere. You may get lucky and find a used one at a reasonable price. The one thing I noticed right away looking on ebay, and what I would be careful about, is some sellers claim their module will replace either one of the 1306 or 1301 modules (which they obviously won't). Stens specifies two separate modules as proper replacements for each of the variants -- which I would personally trust a lot more than any of the others if you decide to go the AM route. Probably better recourse with them as well should you actually experience a failure.
