Tutorial to flash SPI chips with Parallel(LPT1) port

[Bruiser]

So there are some cheap USB flashers on ebay as Drewmerc says.
How do I know the one I am looking at there will work?
Some of the sellers link software called AVR Studio from ATMEL.

eBay item number:
261059205249
$12.99 free shipping from Hong Kong.

The same seller
eBay item number:
261068485925
$14.40 free shipping from Hong Kong. Has two cables instead of one.

Will either of those work for this purpose, which in my case is to put forceware on an SB6121?

This one has a case, but not sure if this will work

If I search for spi flash programmer on ebay I get different results, nothing that looks like the product from USBJTAG.

So what should I order? This is certainly confusing.
I have only used parallel JTAG for SB5101s and the like.

There is also a USB programmer called Blackcat, which I used software labeled Blackcat years ago with a parallel JTAG. This ebay seller

Says SPI flasher, will this work for me? Better, same or different than the ones above?

Thanks in advance.
