If you think the company has a bright future then then the actual entry point is not all that important as long as it is reasonable - it always seems that the perfect entry point was a day or two in the past and a cent or two lower. My approach to small spec stocks is to buy in slowly, learn fast and keep a close eye on it. I only ever buy in once a finished product is ready for sale and I can see market leading technology and increasing demand. I may miss the Disallowed but always happy with a bit less and less risk.
I drank the D13 Kool-Aid last April originally buying a small parcel at a tad over 13c, added considerably at an average of 8c along with a bit of trading when nobody wanted the stock and I am now in the black by 20%. I now have 1m and will add to that as the company progresses before cutting back to free carry when I feel the major price increase has occurred although this is definitely a takeover target for big bucks.
The company is definitely progressing and I would feel confident buying in at or below 10.5c but enter cautiously and add in the dips. As always, DYOR.
