Not to sound snide but obviously you’ve never used a Pace tool. Yes they are expensive, good tools always are. My 30 year old Pace analog soldering/desoldering station is an everyday workhorse with every consumable part available from dozens of sources at very reasonable prices.
There is a reason why even the used equipment sells for the big bucks. The stuff retains its value and replacement parts for every device are readily available. Heaters, switches, cables, you name it, it’s available. Worst case, you buy a whole new handpiece. Sometimes that’s a better choice for things like the desoldering handpiece. I got 20 years out of the original one with more than ten years of daily use on the heater.
Buy junk, use it a couple of times and throw it away. Buy a proper tool and it can last a lifetime.
Sorry, but I've always been unimpressed with Pace, regarding them as overpriced & clunky .
Many years back, the first time I did a High Reliability Hand Soldering course, we were provided with both Pace tools & the locally made Royel brand.
The Royel units were much easier to use, with smaller handpieces, & were definitely equal in reliability, so everybody pushed to get their hands on one
At the time, the Pace units were quite a bit more costly, so Royel should have had the market all to themselves, but that was not to be, & over time, they lost market share due to stupid management decisions, until, in the mid 1990s, when my then job decided to buy a desoldering station for the transmitter site, Pace was virtually the only thing available (still at great expense).
A desoldering station was a mismatch for the particular job which prompted its purchase, so it was done another way, & the Pace sat unused for years.
I kept agitating for it to returned to the Studio where it might be used, but to no avail.
