Bitaxe as Xmas gift for my husband

Hi, I'm looking to get a bitaxe/small miner for my husband for Christmas. He had this on his wishlist and after looking them up I see there are several models to choose from. Some discontinued and new releases. I understand a little about hash rates and such, the more the better, but was wondering if anyone here could recommend a bitaxe model and place to buy? Are there other accessories needed to get one up and running?

Also, if there are any better alternatives for a home beginner's miner for the same approx budget ($200-250) I'd love to hear about those too.

Thanks in advance!
