Looking at buying an SWR meter for my radios and just wondering what to look out for? Choice Magazine don't really review them...

I've narrowed my search down to 6 or 7 models from Strictlyham
- Daiwa CN102L - 1.8-200mhz 20/200/2kw 2 needle $149
- Diamond SX20C 3.5-30,50-54,130-150mhz 30-300W 2 needle $149
- Daiwa CN101L 1.8-200mhz 15/15/1.5kw 2 needle $149
- Diamond SX-200 1.8-200mhz 5/20/200w single needle $169
- Diamond SX-100 1.6-60mhz, 30/300/3kw single needle $169 (Yes I'm aware it doesn't do 2m)
- Daiwa CN801HP 1.8-200mhz, 20/200/2kw 2 needle $175
- Daiwa CN801HP3 1.8-200, 30/300/3kw 2 needle $195.
I've only heard of Diamond as a brand, so maybe some others can make recommendations, as I'm still new to this
