Summary: I bought a Colorado 300 at a local chain store retailer (Best Buys) at a good price, but that's where the good news ended. I'm not into geocaching but wanted this for marking locations on trails that I use for wild mushroom harvesting, so I could return to the same spot one year later. Despite being a really classy looking device, the 300 is a worthless piece of junk.
Summary: I tried the Garman Oregon with the topo maps and immediately returned it. The problem was, that unit in bright indirect light, the map was not visible. The Colorado, with the green shaded base map it came with was not much better, though better than the Topo map (less information than the Topo map).

Summary: Repeat after me: "I will never take this camping. Just like my aluminum water bottle" "Press ONE for ENGLISH" "Doesn't work with MOST SD cards" "Will be obsolete in a year, like all 37 other Garmin models that are released every six months" "All accessories for this unit are lower quality than dollar-store junk" "Convenient 3-paragraph instruction manual.
Summary: First, I am an experienced Garmin GPS hand-held receiver user. I am a long time Garmin user, starting with the Garmin 95XL more than 10 years ago. Besides the 95XL, I have also owned Garmin's eTrek Vista and iQue 3600a. The 95XL and iQue 3600a are primarily aviation based. The eTrek and Colorado series are more general purpose devices. I am a Geocacher from not long after Geocaching started and before it become popular.
Summary: I've owned multiple GPS units over the years, including $10,000+ marine units. Generally had great experience with Garmin. But the Garmin Colorado is a waste of money. Worldwide basemap only sees state highways and above. That's right, for $300+ you get a worthless navigation unit! So you have to buy City Navigator for another $145. Defective disc won't load in any of 5 different PCs. Emailed customer support - no answer in a week.
Summary: bought this as a serious unit for work-related GPS (not having had experience of GPS units before). This unit is going straight back. Multiple freezes, only addressed by removing batteries (that had to supply myself!), virtually useless pre-loaded basemaps (would need to be an alien reviewing Earth as a whole to be satisfied with the level of detail provided). I don't think the unit has been on for more than half an hour and the batteries are on their last legs.

Summary: I purchased one two months ago. The problems with it have included "map up" not working, the battery level indicator has a mind of it's own, the route on the screen moves all over the place and is often just visable in only a corner of the screen. The device has habit of switching off when it feels like it, especially when changing from the map screen to the trip screen. Apart from these major problems there are a host of other minor complaints.
Summary: As noted in other reviews the base map support is very poor. To be asked (at time of writing) to pay another £100+ for maps on top of the base unit cost of £300 just seems crazy. Mine did not even come with batteries. For a unit costing so much I expected it to come with all the bells and whistles. 1 star for value for money, operationally I do not know.
