The 201 is a totally different machine than the 301. In reality the only similarity is they are both straight stitch Singers.
If you found a 301 with all the goodies for $100.00 go for it. That is an excellent price.
Oh, I'll bet your DH has more than 5 tools to use so you don't have to justify anything to him. If he gets cranky tell him to go cook his own meals and wash his own clothes.
