 Hi Mike

>From my experience, MFJ is OK but there are better products. You mentioned
beer cans so I pressume you can build stuff yourself.
If you can get 10m tall Alu tubing I can send you details of how to make it
20/40/80 vertical. 
With two earth rods and 16 radials (8 for 40 and 8 for 80) I managed to work
VK6, ZL etc.etcd. With 100W with ease.
Ready made antenna will cost you around 200£ but I would say you should be
able to buy material with about spending of 1/4 of that.

Vertical is 1/4WL on 20,40 and 80 with capacitive + top loading . It is
rubbish for NVIS contacts but exhibit good low angle.
Also good RX antenna on 160.
