Out of luck, all the 90° triggers I've seen for VSRs run about €100 give or take.
Springer Custom has a very neat "budget" trigger, on the other end of the spectrum Sodium (NA-Mech) makes a supposedly god tier magnetic trigger that isn't that much more expensive than other offerings (bought one yesterday, paid €140 for it, will arrive Monday/Tuesday).
You may want to look at 2nd hand sales, especially AAC T10/T11 owners, those triggers could be obtained for not much and still hold up to some abuse (rated to M120 from factory, but given how much my 1J T11 creeps, you can easily reach 2J on a M120 spring)
