Anyone know what the student discount is over at tequipment? More importantly, which retailer offers the best student discount for Rigol gear?
5%, which is common IME.
You can sometimes get bigger discounts on more expensive items (higher margins built into price; i.e. thousands of $$$ price tags). But because there usually are restrictions regarding advertised prices per their distributor agreements, they may be willing to go lower but are unable to advertise it. Which is why picking up the phone and asking pays off (especially when you see CALL for pricing).
One trick that goes hand-in-hand with this, is to shop at the end of a quarter(sales dept. may be short on their quotas = more willing to make deals to meet them).
Regarding best price on Rigol, TEquipment is the lowest after you apply the EEVBlog discount (ends up @ $375.06 w/ the free gift and free shipping within the continental US). You might get someone else to price match, but I've not seen anyone beat their pricing.
So buy the damn thing already and stop your whining.
Seriously though, the DS1054Z is a steal at this price, so don't overthink it. Pull the trigger and get building/repairing stuff.
