Personally I’d avoid shopping in Europe with a budget under $30k USD, and I won’t take clients there with a budget less than $50k USD. The ‘extra’ costs add up really quickly and by the time you’ve paid flights, hotels, car rental, multiple commissions, PPE, transport, quarantine, insurance, AND factored in the exchange rate, there’s just not much left to put towards the actual purchase price. When we buy in Europe ideally I like to have at least a top 3, often we will vet more than one, and we always get our vet here to review the exam as well (yet another cost).
Keep in mind there’s also a massive price difference between a horse that can do 1.20m and one that is suitable for 1.40m - particularly in Europe where most of them will be jumping in the young horse divisions. Try and be realistic with your goals and don’t buy more horse than you need.
There are very cool horses to be found domestically if you are willing to be a bit creative and look at younger or greener ones, you just need to do a bit of looking around and have some patience. We bought one a few years back for less than your budget. He was 5yrs old and pretty well bred, but very green, a bit of a hooligan to flat and had some wonky xrays. We took a bit of a chance on him, and we got lucky - never had any soundness issues, sold 5 years later for just shy of 6 figures and he’s still jumping very reliably around the 1.30m with an amateur. So it can be done.
