I have owned three Suunto Cores (a Sahara Yellow, Yellow Black, and All Black). The dot matrix screen of the Suunto Core does look very cool. It also does a good job in recording data. I would not recommend the negative screen versions though - black face, green text. They are difficult to read in various lighting conditions.
I have a few other issues with the Cores. The core's Sunrise/Sunset is based on a fixed city database. Changing the time is manual when traveling (instead of being able to change the timezone and automagically changing the time). The biggest issue for me was when may favourite Sahara Yellow Core went through a battery every 3 months even with limited use of the functions. But Amer Sports (the distributor) were great. They took it to have a look and when they had to send it back to Finland to get looked at they replaced it with the All Black (they didn't have the Sahara Yellows anymore).
I have since bought a few solar powered Casio Protreks. My first one was the PRG270 got for just over $100. I have reviewed it elsewhere in comparison with the Suunto and will send you the link.
I subsequently picked up a PRG300 which has slightly larger main font than the PRG270. This is the watch that is now my travelling companion while doing some walks in Europe. I have also given quick reviews of this and compared it with the PRG270 on other sites. There are a few things I like about the Protreks better than the Suunto.
If you don't need the barometer/altimeter and just want the temperature there are cheaper twin sensor watches from Casio that include a compass and thermometer or some of the Edifice series analogue faces that include a thermometer.
There are also barometer/temperature gadgets like this one at Aldi

The clip on ones tend to be more accurate than the wrist worn ones as the wrist worn ones will provide a reading of your skin temperature. What I do when walking is buckle my Protreks to my sternum strap so it gives a more accurate temp. If it is really cold / raining I will strap the watch outside my outer jacket on my wrist.
I've found that my PRG300 is much more sensitive to temperature than my PRG270, which was in then more sensitive than the Suunto Cores.
If you do want to go down the ABC watch route I probably could make some suggestions there as well. There are a few cheaper but still accurate watches out there other than Casio and Suunto. I have some issues with the Casios too, but they are fairly minor.
