Buying my first heat press, level with me

Is there a really huge difference between a $200-250 clamshell heat press (15x15) say by Vevor, or Fancierstudio, versus the $500 entry model from ProWorld , or the $350 HPN model or their $399 model??

I know better than to look at any of the dumb 8-in-1 type machines, but in a basic 15x15 clamshell, how much happier will I be spending $350-500 than that $170 Vevor one that looks a lot like the HPN models in construction?

Also, between the two HPN ones, high pressure vs their craftpro transfer press, what’s the difference and better choice there?

My use is a small e-commerce biz, mainly t-shirts with local inside jokes and sports team fan wear for my city, and sometimes a few small runs of t-shirts for a professional group I’m in, etc. I am a freelance graphic designer so this e-comm and shirts/merch biz is a sideline that I’d like to grow, to take less client digital design work.

I also do craft fairs a few times (5-8) throughout the year. All this to say, I don’t think I will ever need to crank out more than 60 shirts in one week, if that helps provide guidance on what machine will suit me.

Thanks yall!
