Well....let's start with you wanting a cheap board. Why would you even look at a CH board? It's the most expensive board there is. It is a high end enthusiast overclocking board. That's what it was made for. That's why they retain their value. There are many boards @ roughly $50 new that would fit your bill.
I agree, if one of the cheaper boards would do what you'd want, I'd go with that and put the saved $$'s in other components such as a better GPU for example.
However, it also boils down to
what you are looking for in a board. The ROG boards do have features the so called "Lesser" boards do not and you'd have to answer what you mean by "Room to grow" - Any plans in the future for some heavy OC'ing?
Any plans for upgrading the CPU itself later with something along the lines of a hex cored Thuban or even an Octa cored Zambezi/Vishera?
Since an AM3+ can run all chips in the AM3/AM3+ family, it makes sense to look at those so you don't limit your options related to the CPU you'd want to use in the future.
I can say you don't need a ROG board to satisfy the requirements you'd stated. For example, a good Sabertooth 2.0 would do everything you're wanting without being as expensive but know even the Sabertooth is a popular board so it's not going to be exactly cheap. The Sabertooths are capable performers and can post up numbers in many cases like the ROG boards can, the only real advantage the ROG's have over it is those are for OC'ing and gaming vs the Sabertooth being a stripped down OC'er with fewer options.
One such as this
http://www.newegg.com/Product/Product.aspx?Item=N82E16813157479R would be OK but I'd personally go Asus as my first choice if I could followed by Gigabyte, then ASRock as a third choice. I'll also throw in the Sabertooth 2.0 I have was bought open box and it's been nothing but fantastic since day one and even came with all the goodies. I paid about $30 less than a new one would have cost yet it works just as well.
I've been using it way more than I've ran my CHV-Z board but the comparison betwen the two is that the CHV-Z has more options in the BIOS and the range of tunability in the BIOS is greater with the CHV-Z too. For example I can give the chipset up to 1.25v's with the Sabertooth but the selectable voltage range with the CHV-Z goes way higher there. The BIOS itself with the Sabertooth is earier to work with since it doesn't have as many options, simplifying tweaking it - A CHV-Z's BIOS can be a bit overwhelming to figure out BUT the advantage there is if it can be tweaked, there's an option for that.
The questions I'd posted up are what you need to think about before commiting to a purchase. The examples I've posted above about the differences between the models I hope will help with your final choice but in the end, it's all about $$, that being the ultimate factor in your choice.
That's my take on it at least.
