E-Punch Purchase
DVOA has a supply of E-punch sticks available for sale.
Currently, we have some slightly used SI-5 cards (with new straps), on sale for $20.
You can also purchase a slightly used SI-8 card for $30 from our rental pool, and we will swap in one of the used SI-5 cards to take its place. (You can have a new strap.)
Or, we have some brand new SI-8 cards, for the normal price of $40.
The SI-5 and SI-8 cards are similar: the SI-5 model was recently replaced by the SI-8 model, which has the same capacity (30 controls) but is faster at registering a control (330msec for SI-5 vs 115msec for SI-8). If those 2 tenths of a second don't matter to you, they are essentially the same. The SI-8 also has a better casing, so that the protective plastic tip doesn't come off as easily.
You can purchase an E-punch stick at any DVOA local event where epunch is being used.
