@lightweight Across the library sector the numbers get revisited fairly constantly. (At an individual library maybe not because migrations are massive and if you've only just migrated your ILS in the last 10-15 years you probably don't want to migrate it again any time soon if you don't have to... but we still talk to each other and there's always someone looking around because it's been more like 30 years.) Koha is one thing that's probably relatively competitive with other ILSs, because it's solid software and obviously Catalyst has All The Expertise.
But an ILS isn't a discovery layer so if that's what you need (and that's what Sirsi Enterprise is) then the question gets more complex.
As for other software - there's one that I want to bring back from overseas so I've asked colleagues "Hey you self-host this, how about we pay you to host ours too?" and they say "Hell no" instantly. One of my colleagues talked to someone who apparently asked Catalyst about it and the price was apparently not ... "competitive" is a harsh word because there are strong benefits to Catalyst that make it value for money, but if it's money the library doesn't have it's not happening. Anyway that was third-hand and didn't come with the precise numbers so I guess I could contact them myself and ask for our case, but I hesitate to waste anyone's time because I really do know the landscape here Pretty Well.
And then there's some other software I want to bring in-NZ, and {stuff is being complex, vague toot is vague} but if/when we get to the point of actually asking around then Catalyst will definitely be one place we ask. Very happy to hear other names too. I expect the same answer but there are some differences that might change it: worth a try and all.
