And I know neither options beats a real macro lens. I just can't buy that now.
The Raynoxes are not simple close-up lenses. They are achromatic "2-group/3-element lenses , with coated optical glass elements". I've seen a few sets of photos where people compared closeup lenses to Raynox and there's a big difference in distortion, sharpness and CA.
For ultimate quality a dedicated macro wins, but it's not the gap some would have you beliieve. Part of what people are seeing when comparing a Raynox and macro lens is the reduced DOF caused by the longer focal lengths the Raynoxes need. Also the fact that most Raynox users are not mounting them on premium quality lenses.
The DCR-150 has some notable advantages of its own, that's why I bought one despite having a DCR-250 and a D FA 100mm. On your 70-300mm lens, you will get about 1.6:1. That is significantly better than a dedicated macro lens can achieve. At 1:1 and above, the DCR-150 allows you to focus from about double the working distance of a 100mm macro lens. There are also a couple of practical advantages that make a Raynox essential to me; tiny size compared to a macro lens, and no lens changes; just pop-on, pop-off. At the price, everyone should have at least one Raynox.
I would disagree with the suggestion to get a 250 instead of a 150. Yes, the extreme magnification provided by the DCR-250 is a lot of fun, but for you the DCR-150 is the better choice because of the longer working distance, sufficient magnification, less vignetting and because DOF is easier to control.
