Yep, as well as the MIG200 machine, I also bought the matching spool gun.

£127 plus £32 for UPS. Luckily, no Brexit tax payable to UPS on this import, as it's (just) under the £135 threshold. Between £39 and £135, it's assumed that the importer will have already paid (and charged you for) tax.

Not tried it yet (that may take another year or more) but it seemed rude not to get it at the same time as the main unit.
