Yes, SYR is still a business, and there are a couple other similar options.
I don't breed BPs. But when I consider whether a female is too old to breed I look primarily at her overall body conformation, feeding habits, and at her past breeding history (whether she seemed to tolerate breeding well, which is a positive; whether she was pushed to breed early in life, which is a negative and is very common lately).
Whether to breed BPs at all, or whether to breed some morph or other, is worth considering too. Producing some offspring in a less saturated market (i.e. some other species) has a lot to be said for it. Right now on the big classified site there are 36,000 BPs listed, with plain pieds down near $100 (they're also showing up in rescues more frequently), and banana pieds for not much more. Normals het pied (which you'll get 25% of) lately are likely best looked at as culls.
Expo prices lately are much cheaper than online; at the last Tinley Park I was looking at the selection of a vendor who had a 50% off sale on all his BPs, and he went out of his way to point out to me that that was his starting discount and if I were really interested in something he could go lower.
