You won't be able to buy those guns off that website. you can only purchase guns shooting OVER (that's right over) 366 FPS. There's some weird Canadian fire arms laws involved.
I would go with the KJW. It's a pretty good TM clone company with good parts and pretty well built.
But avoid the HFC. I had an HFC Glock that lasted 2 days before going FUBAR. I only put about 200 shots thru it. I also couldn't find any parts for it.
