Silly question of the night but can someone tell me which Circular knitting machine is the best for low budget?

Heya, Thought I'd share the stand I put together for my big Sentro. The trays are a wire type of bottom and I've just used some wing nut to attach it to the cart. I've also attached a digital counter as the one on the machine like to skip a couple every now and again.

Just done this Going to do a scarf like it as well.

Hey everyone! Well it’s Friday again. I almost blinked and missed it! What you doing today? I’m going to make some Santa hats. I’ve got a Christmas fair next weekend so I need to get some stuff made! Have a lovely day
