Hi and welcome to the forum from me too!
Yes I have the Vue, and Weather Display combination. For the price they are great. They will never be a Vantage Pro, but for my situation I couldn't have put a Pro on my section, and got better results than I do with my Vue. By all accounts the Vue is still pretty accurate.
I purchased mine from Blenheim based scientific sales. I've bought a bit of stuff from them and they have always been helpful:

It's a pain to buy but is a blessing when the power goes out, or your computer reboots due to a windows upgrade, or when you decide to go away on holiday.
There are plenty of other brands around too. I used to have an Oregon Scientific, and there are La Crosse and other makes. Generally they are of less quality, but may be a good starting point if you are in a position where you would like to try out the hobby, but not want to commit to many $ at this stage.
The Vue won't do sunshine hours. However what you can do is set up a 1-wire network (sounds complicated but it's actually not too bad) and do it that way. Here's a thread that will get you started:

There is a small cost for it, but it's feature packed and the author of the software who is on this site is very accommodating to adding new features. WD also handles the 1-wire network stuff as well.
Many on here also use Cumulus. I've played with it. It's easy to use and free, and does the basics. I don't think Cumulus will do 1-wire sensors. Both software packages will help you get your data up on the internet.
Hope that's a help. Yell out if you have any questions
