Get the wireless, you never know when you might get a bigger tank, or if you want to sell it down the road it's easier to sell the wireless and you can get more money. I have a non-wireless MP10 I bought used for a great price (knew it wasn't wireless, but was a great deal). I'm now upgrading to a 90 tank, I already bought a MP40 for the new tank and I had to buy the chip for my MP10 for $60 plus shipping and I have to install. Not hard to do, but if I had a choice of only $50 I would have got the wireless.
