You should ask yourself these questions:
1) How often am I going to use it?
2) How much are you going to seal at one sitting?
3) How much are you looking to spend?
The LEM unit I have works fantastic. And because of the current events. It has seen a lot of use with no problems. It can seal for up to 5 hours straight/450 seals without needing to stop and cool down.
Which is more then I need. But, it was a Christmas gift. So whom am I to complain?! But, when I started ramping up my hobby. I knew I needed something different. The wait times between seals was getting old. Hence the new sealer I got for Christmas after I my son heard me P&M about my old one.
Do some research on the vacmaster units as well.
But, up until Christmas I had a a vintage FoodSaver. And it worked good for my needs. I also have my mother's foodsaver that she had for years. And it still performs fine.
What I'm driving at is don't be glamorized by the bells and whistles.
