I have a spare Saleae Logic 8 from an older project. Only used a handful of times. Their software is really excellent if you need to debug a low chance bug related to an I2C or SPI bus, or something else like that. You can have it log for a day, and then go and find the exact issue you had.
They sell for 399 USD now, which is inflated from the past, going on memory.
I'm aware that you can get clones off eBay for peanuts, but the fit and finish of the genuine item is really nice, including the probes, cabling and case.
Let me know what you think is a fair price. About 10 AUD postage domestically, 20 AUD internationally.
