This is a kinda pointless fanzine comment but....
I think Jaycar are pretty good. The bloke who runs it was Dick's partner and his seed capital came from the first buyout. (Woolies?) He knew that competing with Harvey Norman, Good Guys, JB etc was pointless, and he knew that the hobby market was a good niche thing. I gather he is super wealthy (porsche collector etc) and an IPO can be expected soon. Good luck to him.
I can only speak for my local shop in Dee Why, but I have had nothing but good experiences there. Never any parking worries, helpful knowledgeable staff (the dummies are soon weeded out) sells a good range of stuff from kiddy kits to home security etc. Saturday/Sunday morning is not a good time to go but usually there are a few happy campers (like me) in the shop. No serious delays.
They say that Dick started because he was amazed that electronics shops could be so rude, arrogant and useless. He figured that a decent shop couldn't help but survive. Those of my generation (boomer) may remember a shop in Broadway we had to go to for parts in the seventies. Radio Spares or something like that. Great range of components. But you had to take a packed lunch and a sleeping bag to get anything. Of course back then the comics like Electronics Australia used to publish nifty little DIY projects. Not just made in Chine Raspberries, Arduinos etc.
Ahh! the good ol' days, but I say five strs to Jaycar for keeping up the spirit.
Sorry, a fairly pointless post, but there is so much to complain about for us all it's nice to say something good now and again.
