The only available Maiden CDs in the UK at the moment are the enhanced multi media ones. They retail at around the £15 - £18 mark with the double CDs being the more expensive.
Therefore the only way of getting the old CDs, those that are not enhanced, is searching through record collecting mags, record fairs, the web etc. Now since the advent of CDs Maiden have had their back catalogue re-released numerous times and trying to track down the first CD album pressings is impossible.
Below is a list of the first pressing CD albums with their very unusual catalogue numbers. If anyone has these particular CD then please get in touch as I have never seen them:

Powerslave released 11/84 cat no. EMI CZ 81
Live After Death 1 CD released 1/86 cat no. EMI CZ 123
Somewhere In Time released 9/86 cat no. EMI CZ 120
Piece Of Mind released 11/86 cat no. EMI CZ 82

Values for these is open to debate but they are the first albums to be released on CD in the UK.

Seventh Son of A Seventh Son (1988) was the first Maiden album to have the same cat no as the vinyl album and can therefore be considered the first original CD album. Subsequent album releases up to Brave New World (2000) are all valued between the £10 - £20.

Such is the popularity of Maiden and the accessibility of the CD that they do not command such high prices and are easy to pick up. The rarest UK CD has to be the 1992 Donington Live double, limited edition. Cat no CD Don 1. Currently goes for around the £30 mark. Quickly followed by the deluxe hard cover Best Of The Beast double CD (1996) which can fetch around the £25 no problem.
