Yes, a good boot for you is possible. But you need a good bootfitter to pick it for you. The search you need to be doing is for a good bootfitter, not a good boot.
Buying boots is different from buying any other kind of shoe. Ski boots are a tool. They do much more than simply connect the skier to the skis. They transfer the skier's movements to the skis. How well they do this depends on how well they fit.
"Luxury" doesn't matter. Manufacturer of boot doesn't matter. Color, fashion, etc. don't matter. The skis don't know how much you paid for the boots either, so price does not determine how well you can control those skis. The only thing that matters with boots, for a recreational skier, is how well the boots fit.
Well, there's one more thing: you can get a boot that fits well but is too soft. So flex matters. If you find a boot that fits but is too stiff in flex, that flex can be softened. If it's too soft, there's not much you can do.
The boot shell (the hard plastic part), separate from the soft liner, needs to match the foot's anatomy as closely as possible. Length, width, and height over the foot are essential things that need to match. How wide the heel cup is extremely important, as is the circumference of the cuff from the bottom to its top. The bootfitter, after looking at your feet, will remove the liners from a pair of boots and have you stand in them barefooted. This is a shell-fit. How small the amount of empty space is around your feet will determine if the boot is a good fit.
An experienced bootfitter (not a shop attendant or salesperson) will choose the boots that the shop has in stock that come closest to matching these anatomical features of your feet and lower legs. No internet recommendations can come close. A knowledgeable bootfitter needs to see your feet to select the best boots for you.
Know this: a boot that fits well will be tight in an unfamiliar way, but never painful. If a bootfitter finds a boot that matches your anatomy closely, he/she can alter the shape of the plastic liner to match your foot even more closely. The plastic can be heated and "punched" out to accommodate bulges in your feet. Or the plastic can be ground from the inside to make a pocket for that same bony bulge on your foot. Making a too-tight boot larger in spots is the way to go. This service is free. The boot's price actually includes this service. Good luck on finding a good bootfitter near you and getting boots that you'll love, ones that will help you build your skiing skills for years to come.

Hope this helps.
