They are probably the best example for overpriced electronics because of monopoly of some company (=TI).

I've been watching the prices on these since it would be neat to have an 84 and an 89 to do some Z80 and M68K coding on, respectively. Over the past few months the prices have gone from too high to just unbelievable.

TI-84 Plus Silver (15 MHz Z80-based calc with 24K RAM) $173.58 at Newegg and *only* $144.61 at WalMart.

TI-89 (12 MHz M68K-based calc with 256K RAM) $142.99 at Newegg, WalMart price similar.

* Specs from ticalc.org, prices from store websites
