It's not the cost, but the availability. Ever since the demise of vacuum tubes in the 1970's, high-ish voltage transformers have been getting scarce.
If you are willing to PAY for them, there are reasonable units form folks like Hammond. They have crept up in price, although the recent drop in the Canadian Dollar has probably put some downward presure on the price in the States.
these guys for example https://www.hammfg.com/electronics/transformers/classic/261-262 cover off a lot of Nixie applications, using the "filament" windings for the digital stuff.
Hammond has been making similar units for about 70 or more years so no surprises, You an get them through places like Mouser or Antique electronics. they make many of them in Guelph Ontario so even if they run low on stock the back order should be manageable.
