Second what the Rabbiter has said. To be honest the £30-£60 vacuum packers are much of a muchness, it depends on how much you use them but the motors will burn out over time.
I had a £30 quid one which lasted me 2 years and in that time did a lot of work, created a good vacuum quickly and gave a good seal. after that I purchased a Trakaje one
Takaje Deluxe Vacuum Machine costing £200 after a bit of research... And to be honest I was pretty dissapointed.
It is very finnicky to work with, bloody slow to create a vacuum and temperamental when it comes to forming a seal, I thought it was defective but apparently not. My observations are based on comparisons with a £30 machine!! All that said it has lasted 4 years so far and is still working at the standard it was working at when new.
bear in mind that I could have 7 of the £30 machines for the price I don't think it was worth the extra cost.
My advice, buy the cheaper Lakeland one and see how you get on with it, I use a mixture of pre made bags (Very convenient) and rolls of bag material that you cut and seal at both ends to make bags of infinite size (Brilliant for freezing whole fish or Haunches, Or Saddles etc)
Make sure whatever you are vac packing is as dry as possible, sometimes if I want to give some meat or fish away and want a really really neat finish I will put it in a cheap freezer bag upside down, slide it into the vac pac bag and then pull the freezer bag out if that makes sense, this leaves a much cleaner finish on the vac pack bag.
Be careful how you stack or place your vac pack bags in the freezer, especially if your freezer has drawers, friction will wear a hole in the bag as you open/close the freezer drawers or slide stuff over it, this will break your seal an eventually lead to freezer burn.
Hope that helps
