The cost doesn't scare me too much. I'm a firm believer in getting the right tool for the job.
The Hertel seems like a good choice based on a quick read of reviews on Amazon. Thanks!
On tools there are a few good tools and a lot of wrong tools (and expensive tools). Start slow and carefully.
If money isn’t an issue buy the following to start:
A good bench and vice (big investment)
A good iron (heavy with good temperature control is best and generally expensive).
Couple of good plastic scrappers (thick is better)
Brush set (manual to start)
On to tuning (later):
Couple of good files
Edge guide (ideally one for each angle you need)
Base guide (one for each angle you need, note you don’t do bases a lot).
Diamond stones (better quality last longer but cost more).
So budget wise, you can start on the cheap under a $100.00 (wax extra) and range upwards of several thousand and up best quality and fully equipped (yes there are a few members in this category, and those in the know can surely guess who they are).
BTW Hertel FC739 is a good all temp wax, I’d buy direct, likely cheaper than Amazon. Getting into high performance waxing that’s a whole other topic (with a bunch of smoke and mirrors to boot). I sit that discussion out and watch from the sidelines.
