what batteries do you have?
£70 wont get you far if you dont already have batteries and charger?
i have:
the large milwaukee radio (v28) which is great for on site as it has deep base, alot better then dewalt, bosch etc..... but batteries dont last all day cus you have to power big speakers. I use this when on a busy site which needs a good volume to hear well.
the Makita radio which has good sound with small speakers, batteries last a couple of days (18v li-on) nice size, easy to move around job. A good all round radio, suitable for most job areas.
the milwaukee m12 radio, nice small size for tight locations like window sil, good sound for small size, batteries last about a day. This is a great radio if you work in single rooms and loft spaces.
i have also had:
the dewalt radio. Very good sound quality and volume, batteries (18v nicad) last about 3/4 to a day.
