Hi there:
I am currently setting up a website that relies heavily on the gmap, location and comment upload modules. After extensive research, I figured out that all these (and then some) modules were available in Drupal 5 but not yet ported to Drupal 6. The webserver host that I have uses Fantastico to help install Drupal. The problem is the fantastico currently installs Drupal 6.2 only. On talking with the hosting company, they have said that if I uploaded D5 manually, then I have to absorb all the problems that might arise from that, and they will not help me.
Also, if I do install D5 + modules and have my site up and running, do I have to upgrade to D6? I find it a bit frustrating, that while the core is very advanced (almost D7), its hard to get an idea when the modules will be ported in order to plan accordingly. (Before all you developers jump on me, I am just writing my side of the story, I totally understand that you are all volunteers, doing this in your spare time, and believe me, I think the job you all are doing is FANTASTIC!). However, I have been playing around for more than a month, and I am getting to the point where I can't figure out what to do. Do I use the fantastico + D6 and wait with uncertainity, or do I manually install D5 + modules and then stop there.
