Discount strobes

I was browsing Divervision looking for something unrelated, when I came across this:

https://www.divervision.com/collections/strobes/products/ikelite-ds-200-ttl-strobe-40622

Looks like they're clearing some old stock - Ikelite DS200 is discontinued, heavy, bulky, and only takes electrical sync (although optical adapters are available), but unless the battery packs have degraded beyond usable capacity, $249 for a 200 W/s strobe is still a tremendously good deal.
