Original Hi-Pro

Price
Old Junk Serial Hi Pro $99
Serial to USB adapter $6
Pair of CS44 Cables $50
Pair of Flex Strips $20
Free Shipping $0
Total $175

Upon further reflection this is not a bad deal. Since the cheapest we found cables and flex strips was $50 and $20 ($70 total) and if you are willing to use a device that pre-dates USB, then you can get this deal for $50 cheaper than a mini Pro with CS44 cables and flexstrips. That is assuming flexstrips are included, the OP just said programming cables.

Since the Serial to USB adapter is included you can avoid connectivity problems that arise from adapters that don’t support the required speed. This was a major concern of mine. But since the adapter is supplied you should be good to go.
