I did a lot of searching before i bought my current Sirio 2016, the guys on here suggested a few and I looked at them all.
as many of the guys have said, normally the bigger the antenna and the higher you can mount it the better.
I guess a lot of it my case came down to price, where I could mount it and if I would P!ss of the neighbours in some way.
The two I decided on were;
Sirio 2016, due to it's easy tuning, height and smaller ground planes, easy assembly and flexibility due to wind. I picked it up for approx £125 from Knights.
The President Himalaya was my alternative, unfortunately I could not find anyone with stock when I was buying. It is pricey though at £168.
One thing I would suggest is that you buy good quality coax as this makes a huge difference when you have a run of cable to the antenna, suggest RG-213 if you haven't done so already.
Hope these are some food for thought.
Good luck with the hunting.
