I was in a similar situation when I got started and didn't have the money to buy a laminator immediately after purchasing my printer. For smaller jobs I had a 32" BS and I also invested in a 54" BS for larger stuff. The 32" was/is very easy to handle and makes quick work of small stuff. However, the 54" BS can be cumbersome and flexes a lot especially on the ends. (This is coming from a guy that is 6' 5" and has really long arms.) I was able to make it work for nearly a year, in fact I was able to laminate an entire 24' box truck wrap with the 54" BS and only ruined 1 print. Yes, it was a pain and I would never do it again...
However, fast forward to today and the 54" BS sits in the corner. Too many issues with silvering and tiny bubbles due to inconsistent pressure from it flexing. Don't get me wrong - if it's all you got, it's all you got and it will work to a certain degree. However, $2k will buy a really nice laminator from US Tech that will pay for itself in short time. FWIW - I still use the heck out of the 32" BS I have, for small jobs it beats threading up the laminator and it's shorter length keeps it stiffer and I have less problems with bubbles or silvering than it's big brother.
Realize with any BS product, it's all about technique and practice.
