DSL Filter

I'm looking for a DSL Filter preferably a double to connect the land line and the broadband connection. The name of the filter Eircom provided me with is Excelsus Z-Blocker - Model Z-230TJ. It's broken
I found one online for USD 9.99.
Does anyone know where in Dublin city centre I will be able to buy one.

Thanks.

I saw some (not this model or brand) in Dixons in Jervis over the weekend - over to the left near the checkouts.

Thanks. I'll drop in and check them out.

Try ringing Eircom Technical Support to get new ones...mind you it might take a while. I had to get new ones from BT, it took yonks but finally they arrived for free. I was willing to wait as I couldn't get them in the shops.
