OK, I've taken the tablets: summary, Add to Event can be tried with £24, and can generate instant results. ( Can also eat £24 very quickly, it used to be a lot cheaper). Downside can be that many leads have a low budget and Sid quoting for them.
NaD costs from £99 a year, but its leads are
FREE! . They're also more realistically priced on the whole, and you get other benefits too.
Also, networking. Wayne will know if Rambling Sid Rumpo's happy band* have meetings in your area. All meetings are worth showing your face at, I've learnt a lot from them, and on occasion picked up cheap kit. Good luck.
* If you ever listened to "Round The Horne" you'll know one reason I didn't join NADJ this June when my PLI was due for renewal.
