I have searched "Landscape Design Software" and found that everyone seems to recommend the high priced programs. I'm wondering if anyone can give me some input on the "Realtime Landscape Pro, V.5" software? I really can't afford $1,000.00 + for this, and was interested to know if this program can help me get started. I wanted to know if the irrigation part can figure a design by way of PSI and flow? Is there any feature that helps design outdoor lighting? Any input will be greatly appreciated. Thanx.
