If I had 25k to spend, I would first ask myself a few questions.
What am I going to use the printer for? Is it for production? Prototyping? Rings? Do I need to print larger items such as bangles?
How long would it take me to make the money back for that purchase? If it will take more than a year, chances are by the time I'm done paying for it, something better and cheaper will be on the market.
Am I doing my own casting, or outsource it? In my experience, most casting places are currently staying away from casting RP resin. They just don't want the risk of messing up your prints. They all ask for wax. There are some place that cast the RP resin, but they want to be the ones to print it on their own machines.
Service fees? Most of these high end machines require expensive service contracts?
Resin? Most of these high end machines have resin that cost more than 10 times what the form1 resin costs.
Do I really need an expensive 3d printer? For 25K you can print many many rings at a service bureau, and even more if they are doing the casting also.
So as you can see it's not a simple question to answer. If it's just about "I have to have it"....I would probably go with Envisiontec or the Kevvox, or if I need problem free casting, the Solidscape wax printers (these may be more than 25k)
What I love about the Form1, B9 creator, and similar printers.... they give us relatively great quality for incredibly low prices. And that way you can work less to pay off your machine, and focus more on creativity and ideas.
I know lots of jewelers in the Downtown LA area who have the most expensive EV printers, the DWS, Solidscape... and they now look like idiots, because the "guy down the street" can print rings for $15 a pop for them, rendering their machines useless.
Stick with the Form1 for now. Unless they don't release a castable resin in a month or 2. The b9 is a great option too, especially of the high resolution and with the castable resin.
If you want problem free and cheap 3d printing...the answer is simple...outsource it.
