Are you *sure* you don't mean graphics cards?

o If it is graphics cards, then it's by add-in card options for
  various models, affording various levels of quality. I still haven't
  worked out why people spend 400ukp on a Video, 350-450ukp on a TV
  which could cause an eclipse and then try to watch video on PCs ;)

o Monitors will cope well with such, they'll sit there & yawn. 
  Probably power off out of boredom.

Quality is largely dependent on the compresion etc used and partly
on the quality of the video decoding etc, not the monitor per se.

PS. The person who was thinking about bkup-devices on the Evesham PC:
    Try a Zip (some find not so reliable), JAZZ or Panasonic PD drive.
    o The PD drive is admittedly anaesthetising at 650MB optical
      cartridge *writing*, but it's an ok 4x CD-Rom as well. It is 
      SCSI and ~ 366-396ukp ex VAT. Cartridges are ~33ukp for 650MB.
    o Only other alternatives are the Travan tape drives, which I 
      can't help but read as Trabant.

PPS. Re (E)IDE vs. SCSI CD drives:
o SCSI ones are best fitted to a Bus-Mastering SCSI card, eg, NCR
  810/815 (37/43ukp) which has the benefit over (E)IDE of lower CPU
  load during data transfers. If you're playing Video, then using
  60% of your CPU for P.I.O. (EIDE) transfers doesn't leave much for 
  working on the data (ie, decompressing video) afterwards.

  Win95 isn't quite so brain-dead it doesn't know what to do with 
  bus-mastering, but NT & OS/2 drool over it. W4WG/3.1 is clueless.

You may wish to put the $ somewhere else however, eg, RAM, s/w, 9017E.
