I'd probably rather stick with a steel case 205 if possible, despite the low range, it's more of a driver than a wheeler for me and I'm trying to do this as affordable as I can so I'd like to avoid buying a new TC.
Yes, the 241 case is aluminum. Really, the 241 has only two weaknesses which are fairly easily remedied. First, being the aluminum case which you can take care of with a good skid plate. Second being the slip yoke on the rear output. A JB Conversions SYE (slip yoke eliminator) takes care of that, and it shortens the overall length of the 241 by roughly 4".

I don't really see the driver/wheeler argument being valid. Both cases have strengths in each area. If you told me you were gonna wheel the snot out of your rig and had plans for a doubler in the future, then absolutely go with the 205. If you're gonna put 700+hp to the ground, then yes, the 205's gear setup would holdup better than the 241s chain. If you want to be able to say, "I've got a 205", then keep the 205. If none of those are true, I still have to lean the direction of the 241 because it mates up cleaner to the 700, it has a deeper low gear, it's lighter (by about 50lbs), with a $60 clocking ring you can clock the 241 up to give you more ground clearance than a 205, and you can pick one up fairly cheap.
