I would recommend a fixed-coil cartridge (a.k.a MM). Searching the web I found a few that your friend might consider. All, save one, are less than £150.

Goldring E3 (Around £99)

Sumiko Rainier (£160)

Audio Technica VM320EB (£144)

Audio Technica VM520EB (£105)

Ortofon 2M Red (£99)

Nagaoka MP110 (£130)


I should add that I have absolutely no experience of any of the cartridges listed above, but are some that I might look at given the record deck and budget.

Hope it helps.
